The question of hate in Heaven has always been a theologically loaded one, but along with Sin as the first female being of the universe comes the question of sex in Heaven. The one reference to this comes from Sin herself when she tells Satan her story: "[...] such joy thou took'st/ With me in secret, that my womb conceived/ A growing burden.", (II, 765-7). The question of joy in Heaven may be much less interesting than that of hate, but that of physical, sexual joy, can be thought of more peculiar (though Milton clearly portrays a vision of sex that is sinless with Adam and Eve and how promiscuous they get, especially considering the above mentioned future children they expect to have to help them with their daily work). Thus sex per se is not automatically a sinful thing, yet what to think of Satan and Sin's relationship? Well, for one, she is his very daughter, and while Milton could conceive of sinless sex, I would not suppose he would consider sinless incestuous sex (given that incest is not only a religious taboo but very much so an inherently human one, even atheists do not copulate with their daughters, generally). This incestuous nature is the first clue that something is not quite right, even in Heaven. The second point I ask myself about is whether the "joy" Satan took with Sin was shared. Indeed, Sin nowhere tells that she herself enjoyed the act, or even agreed to it, and so it is not inconsiderable that she may in fact have been raped by Satan. Raped in Heaven and raped in Hell? The story of Sin being what it is, that would not be unsuited. A third point is that this relationship with Satan was lived "in secret", (II, 766), and that too brings up some questions. First of all, can there be secrets in Heaven? Whereas we have seen that there could be hate and even sex in Heaven, whether or not there can be secrets is much less certain. God is omniscient, after all; so there can be no secrets. What is most interesting, however, is that likely Satan believed there could be secrets and that God did not know everything. That argument is of major importance for critics who argue that Satan was tricked into doing what he did and that ultimately God is responsible for everything that happened, Fall included. This notion of secret also brings the fact that there was something to hide, something possibly wrong that needed to be kept from others, something possibly sinful. If Satan felt the need to hide, then surely he must have thought that what he was doing was not all that correct. But why exactly? If he thought the joy he took with his own daughter a thing not to do, then why did he do it at all? This would mean he knowingly chose to do evil. Any reason for the hiding can only be conjectural, since neither Sin nor Satan explicitly explains the why of the secrecy. There could be several origins: Satan could have been aware of the incestuous nature of the relation, and that it was "wrong", he may have wanted no one to know about the affair, though why exactly I do not know (except for the reason previously mentioned), perhaps he discovered a new kind of joy with Sin and that raised suspicions in him (and perhaps also he did not want any other angel to find out "sex", maybe Satan discovered sex, since Sin is the first female being of them all; although angels are traditionally genderless, Milton refers to them as males: Satan is a "he" and so are the other angels), lastly, if Satan was indeed raping Sin repeatedly, then he would not have wanted others to find out his crime. Whatever the reason, Satan, according to Sin, decided to keep the act a secret, thus admitting that he was not entirely at ease with the relationship and that probably, he was experiencing evilness.
